Chrysanthemum plant named ‘Zanmuhots’

ABSTRACT

A  Chrysanthemum  plant named ‘Zanmuhots’ characterized by its large sized blooms with dark red ray florets and prolific branching; natural season flower date September 9-13 (week 37); blooming for a period of 5 weeks.

Botanical designation: Chrysanthemum×morifolium Ramat.

Cultivar denomination: ‘Zanmuhots’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar ofChrysanthemum plant, botanically known as Chrysanthemum×morifoliumRamat., commercially known as a garden mum, and hereinafter referred toby the cultivar denomination ‘Zanmuhots’. ‘Zanmuhots’ is a product of abreeding and selection program for outdoor pot mums (garden mums) whichhad the objective of creating new cultivars with a double typeinflorescence, a natural season flowering date around week 37, bloomingfor a period of 5 weeks. ‘Zanmuhots’ is a seedling resulting from across of the female parent id 24446 (not patented) with the male parentid 310538 (not patented). Plants of the new cultivar ‘Zanmuhots’ differfrom plants of the parent in growth habit; the plants of the femaleparent are more spreading in shape compared to those of the seedling,while those of the male parent are more erect in shape than those of theseedling.

The new and distinct cultivar was discovered and selected as a floweringplant by Henricus Cornelius Maria Jacobs on a cultivated field inRijsenhout, The Netherlands in 2010. The first act of asexual productionof ‘Zanmuhots’ was accomplished when vegetative cuttings from theinitial selection in 2010 were propagated further in a controlledenvironment in Rijsenhout, The Netherlands. In summer, about 6-8 daysare needed to initiate roots in cuttings of the new cultivar, afteranother 5 days rooted plants are formed. The new cultivar has been foundto retain its distinctive characteristics through successivepropagations.

BRIEF DESCRIPTION OF THE DRAWINGS

The present invention of a new and distinct variety of Chrysanthemum (ofabout 16 weeks) is shown in the accompanying drawings, the color beingas nearly true as possible with color photographs of this type.

FIG. 1 shows a plant of the cultivar in full bloom.

FIG. 2 shows the various stages of bloom of the new cultivar.

FIG. 3 shows the various stages of foliage of the new cultivar.

DESCRIPTION OF THE INVENTION

The observations and measurements were gathered from plants in theperiod of 15 to 22 weeks of age, grown outdoor in Rijsenhout, TheNetherlands, under natural day length and temperature and planted inweek 23 in 2013 (with a warm summer), receiving drip irrigation. Thenatural blooming date of this crop was September 9-13 (week 37). Theaverage height of the plants was 30 cm. No growth retardants were used.No tests were done on disease or insect resistance or susceptibility. Notests were done on cold or drought tolerance. This new variety produceslarge sized blooms with dark red ray florets blooming for a period of 5weeks.

From the cultivars known to the inventor the most similar existingcultivar in comparison to ‘Zanmuhots’ is ‘Jenny Wren’ (U.S. Plant Pat.No. 10,213). When ‘Jenny Wren’ and ‘Zanmuhots’ are being compared thefollowing differences are noticed: (1). Inflorescence size. And (2).Growth habit. (1). Inflorescences of ‘Jenny Wren’ are smaller in sizethan those of ‘Zanmuhots’. (2). Plants of ‘Jenny Wren’ are lessball-shaped than those of ‘Zanmuhots’.

The following is a description of the plant and characteristics thatdistinguish ‘Zanmuhots’ as a new and distinct variety.

The color designations are taken from the plant itself. Accordingly, anydiscrepancies between the color designations and the colors depicted inthe photographs are due to photographic tolerances. The color chart usedin this description is: The Royal Horticultural Society Colour Chart,edition 2001.
